Electrical poblem at campground

[richard5933]

My problem is that the spots where I would have attached grounds for lights has been covered by panels, cupboards,etc.

Same problem on the Custom Coach work. They have terminal strips hidden behind lots of things. They also seemed to think it was okay to have both 12v and 120v share an unlabeled terminal block. Created quite the unexpected jolt. Kind of surprising from Custom Coach.

The early years of  coach converting produced some crude work compared to todays standards. Same on our former 4104. A converter could be fantastic on woodwork and upholstery and be weak on plumbing or electrical.

Grounding to aluminum does cause issues over time from corrosion starting. They make a paste for household electrical that helps deal with  connections at the panel.
I use this, although mine is in a squishy bottle I bought years ago. I think Amazon and Lowes also sell it.

Years ago the old electricians wouldn't dream of making a connection without the little bottle of CT4B Blackburn .This was before Noalox ever appeared on the scene
